If anything the skew within the platforms is to prioritize pro-palestinian views https://twitter.com/committeeonccp/status/173279243496103143...
It also seems like these platforms create (rather than support) anti-Israeli views: https://twitter.com/antgoldbloom/status/1730255552738201854
US views skew pro-israel, and GenZ is closer to 50/50, so if there's something going on online, it's not in favor of Israel.
It's probably relevant that there are 1 billion Muslims to 16 million Jews, and that the largest relevant population of pro-Israeli internationals is India and Indian Hindus, and they are not on TikTok (blocked in India).
But conflating anti-Israeli views with anti-Semitic views does a disservice to Jews and Palestinians alike.
Anti Israeli government: It's not antisemitic.
Anti Israeli people: It's antisemitic.
Criticizing Israeli settlements in the West Bank is not antisemitic. But suggesting that Israel has no right to exist as a Jewish state is antisemitic as it implies ethnic cleansing.
Both are arguably criticisms of the Israeli government.
We have seen that in the western world that we do not abide the idea of ethnostates, e.g. it is considered bigoted to oppose unlimited migration from refugee countries into Europe or North America. Likewise it is not okay to say "only X race or Y religion can be in government". Why is it okay in the case of Israel?
Jews lived and existed before Israel was established and they were not ethnically cleansed.
I don't really have a dog in this fight and I'm not trying to controversial, I'm genuinely curious because the choice you offer seems like a false dichotomy.
